Sound DB level was below 95 DB (for all states that comply with CA law on that). 98's dyno may be more apples to apples for you though.

Sounds very nice but not annoying in any way due to the sub silencers and looks aswesome. Tips are adjustable in lenght as well so it's nice for guys who are running the diffusers and rear skirts.
According to Import Parts Pro, the Nismo exhaust adds 5.4HP and you're saying you got approx 5HP more than stock Nismo, then it might be safe to say this is a 10-15HP exhaust??? I was hoping it would be more in the 15-20HP but I can live with 10-15HP increase.
